Reading data from a URL and putting it into an ArrayList

Question

Hi. I am trying to read a text file from a dropbox URL and put the contents of the text file to the ArrayList. I was able to read and out print the data by using openStream() method but I can't seem to be able to figure out how to put that data into an ArrayList

URL pList = new URL("http://url");
  BufferedReader in = new BufferedReader(
        new InputStreamReader(
        pList.openStream()));

  String inputLine;

  while ((inputLine = in.readLine()) != null)
      System.out.println(inputLine);

would appreciate the help ?

Answer 1

List<String> list = new ArrayList<String>();
while ((inputLine = in.readLine()) != null) {
    list.add(inputLine);
}

Answer 2

Try something like this:

String inputLine;
ArrayList<String> array = new ArrayList<String>();

while ((inputLine = in.readLine()) != null) {
    array.add(inputLine);
}

Answer 3

It depends on what you want to do:

• Store multiple DropBox files in an ArrayList, where 1 item represents 1 file

  Use a StringBuilder to stitch all the lines together to one string.

   List<String> files = new ArrayList<String>(); files.add(readFileUsingStringBuilder(pList)); public static String readFileUsingStringBuilder(URL url) { StringBuilder sb = new StringBuilder(); String separator = ""; BufferedReader br = new BufferedReader(new InputStreamReader(url.openStream())); String line; while ((line = br.readLine() != null) { sb.append(separator); sb.append(line); separator = "\\n"; } return sb.toString(); } 

• Store each line of the file in a record of the ArrayList

   String inputLine; ArrayList<String> array = new ArrayList<String>(); while ((inputLine = in.readLine()) != null) { array.add(inputLine); }
